Going to copy-paste the comment I posted on the cross-post:
I am going to temper my expectations a bit, since the article is specifically singling out their clause on accessing additional games. But at the same time, I am huffing the hopium since Sony has upstreamed PlayStation controller drivers to the Linux kernel, so they might be receptive to supporting SteamVR, Steam Link or something equivalent, if possible.
(No, before you ask, I’m not expecting Linux support on PSVR2.)
